Answer:
= - 12
Step-by-step explanation:
To find the 5 th term in the sequence, calculate the 3 rd and 4 th terms, that is
= - 2
-
- 1 ← substitute in values
= - 2(1) - 2 - 1 = - 2 - 2 - 1 = - 5
= - 2
-
- 1 ← substitute values
= - 2(- 5) - 1 - 1 = 10 - 1 - 1 = 8
= - 2
-
- 1 ← substitute values
= - 2(8) - (- 5) - 1 = - 16 + 5 - 1 = - 12
The equation for resolving couples will come in place
Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.
<h3>Couple moment and Cartesian vector</h3>
Couple moment:This looks at the product of the forces acting on a body( in this context a steering wheel ) by the perpendicular distance that exist amidst the forces.
Cartesian vector:this is the representation of unit vectors by i and j along the x-axis and the y-axis, respectively.
Therefore, in calculating the <em>couple</em> moment t acting on the steering wheel, the equation for resolving couples will come in place
Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.
